OM extension erroring out with getAttribute() on null object when trying to fetch EFF Valuee

Summary:

We have requirement to apply hold on sales order by validating the EFF attribute values. However, if the EFF value is not populated with any value the extension is erroring with getAttribute() on null object.

If the EFF attribute populated, the extension is working. I need to validate if EFF attribute and proceed further in the extension.
